1. Advantages of our solar generation system with batteries

In cases of emergency, Edison Power’s solar generation system (+batteries) can provide water pumps, computers and other electronic devices with electricity. It does not require any manual switchover; when the power goes out, it starts to operate itself automatically, providing power to those devices.

Moreover, there is an electricity buyback program in Japan, through which the power produced using the system can be sold to utility firms. This buyback can be continued up to 20 years guaranteed.
During the daytime, the cost of electricity can be saved using the “peak-shift” function.


2. Circuit Block Diagram

  • During the daytime, electricity is generated using the solar panels, and then sold to utility companies.

  • Normally, both critical & general devices are run with grid-connected power from utility companies.

  • In cases of emergency, the critical devices are automatically connected to UPS to be able to run properly.     

  • Even if the power outage continues, the system can still be recharged with the solar panels using the self-operated power conditioner.

  • Remote monitoring is also available upon request.

  • The capacity of batteries & solar panels can be customized to suit your needs.

  • With the timer function in the batteries, the system can be recharged during the night instead of the daytime. (peak-shift)

    *”Critical devices” are the ones that should function at all costs at times of natural disaster.
